An type for Lucky framework Avram that's encrypt a string before saving to a database and decrypts when getting it from db.

it use defaults from Lucky's message encryptor class, which is using when last checked aes-256-cbc and the digest is sha1

You only need one column, as both the iv and the data is saved in one, splitted.

1. Add the dependency to your shard.yml:

   dependencies:
     lucky_encrypted:
       github: microgit-com/lucky_encrypted

2. Run shards install

• add require "lucky_encrypted" in shards.cr

• Create an column for the encrypted string you want to save with lucky migration, i use otp_secret as example.

• set a config for LuckyEncrypted:

  # In config/lucky_encrypted.cr
  require "./server" # To get the configuration from the server
  LuckyEncrypted.configure do |settings|
    settings.secret = Lucky::Server.settings.secret_key_base
  end

  you can use lucky's secret key base or generate a different secret with lucky gen.secret_key

• Add the type LuckyEncrypted::StringEncrypted as type for that column in the model:

    column otp_secret : LuckyEncrypted::StringEncrypted
  

it shall now work. (famous last words)

using stdlib spec and all. so just use the test and so forth.
